A 4" inlet splitting to twin outlets, drawn as a proper lofted Y — not two cones welded to a box. For charge pipe, intake plumbing and any place you need to take one big pipe into two without wrecking the flow doing it.
Choose your outlet size and your end style. Wiggins clamp flange or plain weld tube, 2.0" through 3.5" outlets.
What you download
- STL for the configuration you pick — outlet size, Wiggins or tube end
- 4" inlet → dual 2.0" / 2.5" / 3.0" / 3.5" outlets
- G3 continuity loft — the transition is smooth in curvature, not just tangent
- Instant download at checkout. Nothing ships.
Two licence tiers, and they mean what they say
- Personal / Self-Use — $49. Print it for your own vehicle or your own shop's work, including a customer's car.
- Commercial Shop — $299. Print and sell finished parts made from this file. Twelve months, renewable.
Neither tier permits sharing or reselling the file itself.
Printing it in metal
This part is drawn for metal printing. If you'd rather buy the finished part, the printed aluminium and 316 stainless versions are listed separately.
Drawn by James Goertz, G1Pro. Building intake manifolds by hand since 2009 — hundreds of them.
